The Optimization and Application of Elastic Balancing Device for Rolling Mill

轧机弹性胶体平衡装置的优化及应用

Preferred position for 2300 valves is in a horizontal line with spring chamber up.

对于系列2300阀门，首选的安装位置是在水平管线上，其弹簧隔膜朝上。

If we let go, the elastic energy, as the spring passes through the equilibrium point, is converted to kinetic energy.

如果我们释放弹簧，那么弹簧经过平衡点时，弹性能就转变为动能。
